[Denemo-devel] LilyPond beaming bug?

[Richard Shann]

I think I have found a LilyPond beaming bug (I'm on LilyPond 2.8.7 as
delivered with Debian Etch). In 3/4 time a dotted quarter note followed
by three eighth notes is beamed as if it was in 6/8 time.
If this is a LilyPond bug then we could be fixing it in the Denemo
output - below is an attempt by me to do this, attached is the relevant
Denemo file.
Questions: is this a LilyPond bug? 
Is it present in all versions? 
Can it be fixed using an override like the ones I've experimented with
below? (They are commented out in the file).
I won't get time to research this more just at present, but if there are
any musical notation gurus around...
